NCT07532694

Brief Summary

This randomized controlled trial evaluates the efficacy of diode laser-assisted non-surgical periodontal therapy in kidney transplant recipients with periodontitis. Eighty participants will be allocated to two parallel groups: scaling and root planing (SRP) with adjunctive diode laser therapy or SRP alone. Clinical periodontal parameters, blood biomarkers, radiographic findings, and subgingival microbiome profiles will be assessed at baseline and during follow-up. The study aims to determine whether adjunctive diode laser therapy provides superior clinical and biological improvement compared with SRP alone.

    Baseline, 1 month, 3 months, and 6 months

  • Change in gingival index (GI)

    Baseline, 1 month, 3 months, and 6 months

  • Change in plaque index (PlI)

    Baseline, 1 month, 3 months, and 6 months

  • Change in OHI-S

    Baseline, 1 month, 3 months, and 6 months

  • Change in platelet count

    Baseline, 1 month, 3 months, and 6 months

  • +3 more secondary outcomes

Study Arms (2)

SRP + diode laser

EXPERIMENTAL

Participants receive full-mouth scaling and root planing combined with adjunctive diode laser treatment according to the study protocol.

Procedure: Scaling and Root PlaningDevice: Diode Laser

SRP alone

ACTIVE COMPARATOR

Participants receive full-mouth scaling and root planing alone according to the study protocol

Procedure: Scaling and Root Planing

Interventions

Conventional non-surgical periodontal therapy performed according to the study protocol in both groups.

SRP + diode laserSRP alone

Adjunctive diode laser application to periodontal pockets after SRP in the experimental arm. Device specifications, wavelength, power settings, mode, fiber size, number of applications, and treatment sessions should match the approved protocol exactly.
